COMMENT  = Makefile to build libe_sqlite3.so from sources in https://github.com/ericsink/cb/tree/master/sqlite3 and https://github.com/ericsink/cb/tree/master/stup
LICENSE  = Apache 2.0

# libe_sqlite3.so is the native library for linux provided by SQLitePCLRaw nuget package.
# Since the (cross) toolchains used for creation in https://github.com/ericsink/cb provide newer libc versions, 
# these libraries depend on GLIBC 2.28.
# Such toolchains are used since SQLitePCLRaw 2.0.5.
# 
# As .NET 8 and .NET 9 do not have such restrictions and run well on DSM 7.1.1 with GLIBC 2.26
# and on DSM 6.2.4 with GLIBC 2.20, we create libe_sqlite3.so here with the toolchains from 
# Synology for compatibility with DSM.
